ERS CO2 is a LoRaWAN sensor for high accuracy measuring in indoor environments and is a great sensor for smart buildings, dynamic workspaces, or climate control. It has a discrete and minimalistic design and is equipped with internal sensors for measuring CO2 level, temperature, humidity, light, and motion. The sensor can easily be configured with a mobile app and the expected battery life is up to 10 years (depending on transmit interval, data rate and usage environment).
